Well, if you are in California it makes sense that the California Air Resources Board mandates fuel quality, but there are a lot of posters on this site who aren't in California. Regulations differ by geography.

Also, within California, the sulphur content and total aromatic hydrocarbons are regulated, but I am not so sure about the cetane number, and the minimum acceptable cetane is a BMW specified figure. I am pretty sure that fuel lubricity is not specified either.
